COLEOPTERA-CARABIDAE OF THE JUAN FERNANDEZ ISLANDS 637 



and impunctate. Microsculpture, underside, and legs as in P. selkirki, but the 

 metepisterna are only a third longer than wide, and the dilated apical part of 

 the metetibiae is only a half wider than the basal part. 



In this species, as in the two preceding ones, the outer striae of the elytra 

 converge and become very narrow behind; as in the genus Abax, there is a 

 ridge, though a slight one, in the marginal channel of the elytra behind, and 

 as in Tapinopterus the hind lateral seta of the prothorax is (apparently) wanting.
